Jan 1, 2025
This Mendelian randomization study assessed whether duration of mobile phone use is causally related to stroke outcomes using GWAS-derived SNP instruments. The inverse-variance weighted analysis reported a significant increased risk for large artery atherosclerosis (LAAS) with longer mobile phone use duration, while…

This theoretical/physics paper examines how an in-plane uniform electric field affects the de Haas-van Alphen (dHvA) effect in graphene. It reports that magnetization, magnetic susceptibility, and dHvA oscillation behavior depend on a dimensionless parameter β = E/(vF B), with divergences described at a critical…

This study reports slow relaxation of magnetoresistance in selectively doped p-GaAs-AlGaAs structures following application of a magnetic field. The authors emphasize efforts to rule out temperature fluctuation artifacts and state that the main relaxation features remain. They interpret the phenomenon using a…
Biased bilayer graphene: semiconductor with a gap tunable by the electric field effect.

Jan 1, 2007
This paper reports that the electronic gap in bilayer graphene can be controlled externally via a gate bias (electric field effect). Using magnetotransport (Shubnikov-de Haas) data and a tight-binding model, the authors extract the gap as a function of electronic density. They report tuning the gap from zero to…
